Wet OSB Should be Usable

Dear Tim: I have some 4x8 sheets of 7/16" OSB that I have been storing pending the construction of a private 10'x20' storage shed. The OSB got wet and appears to be waterlogged. It is holding together though quite well, and not breaking up. Will it be usable as sheathing for wall and roof construction and will it dry out? Thanks, Dean.

Dear Dean: The OSB board will indeed be fine if you are sure that it is not falling apart. It is actually made with special glues that can get wet repeatedly. I suggest you let them dry in a shaded area, not in direct sunlight, and do so as soon as possible.

  1. I have a house that was framed and the builder went under. the house sat for a year and now we want to continue construction. the town says we need to remove all the OSB from roof and first and second floors. if the OSB is not falling apart and is still rigid I believe we are OK. The board is black where exposed to the sun. Is it still OK??
